Triangle Calculator

The triangle is limited to lattice points in the range . Drag the points , , and to generate new triangles. Hover over lines and special points to get a popup with equations or values. The program calculates triangle centers:

• incenter , the center of the incircle, where the angle bisectors intersect,

• centroid , where the medians intersect,

• circumcenter , the center of the circumcircle, where the perpendicular bisectors intersect, and
